Problems solved by technology

The triangulation method requires a lot of positioning parameters in the application, and it is very cumbersome and time-consuming in the calibration of the measuring equipment. If a certain parameter in the system cannot be accurately obtained during the actual measurement, it will cause errors in the measurement data
The measurement electronics are far more complex than the pulse method

Abstract

A novel tunnel profiler comprises a horizontal base and a frame.A horizontal main transverse shaft which can rotate around own axis in a power-driven manner is arranged on the frame.A first main observing device is fixed on the main transverse shaft.An auxiliary shaft rack is fixed on the first main observing device.An auxiliary shaft which can rotate around own axis in a power-driven manner is arranged on the auxiliary shaft rack.A first auxiliary observing device is fixed on the auxiliary shaft.A first main observing line and a first auxiliary observing line are located on the same plane.A main dial is mounted between the corresponding parts of the main transverse shaft and the frame.An auxiliary dial is mounted between the corresponding parts of the auxiliary shaft and the shaft rack.The novel tunnel profiler has the advantages that the novel tunnel profiler can be directly used for tunnel section measuring, complex and time-consuming calibration in advance is not needed, influence of factors such as external temperature on equipment is reduced greatly, ranging precision requirements can be satisfied completely, and convenience in operation is achieved.

Description

technical field [0001] The invention relates to a tunnel profiler. Background technique [0002] Excavation is a key process of tunnel construction period and cost. Over-excavation not only increases the project cost due to the increase of slag discharge and lining volume, but also directly affects the stability of surrounding rock due to stress concentration caused by local over-excavation. Under-excavation will directly affect the thickness of the lining and cause hidden dangers to the quality and safety of the project. Various data show that the control of overbreak and underbreak has an important influence on the reliability and economic benefits of the tunnel structure. Tunnel profilers are used for fast and accurate measurement of tunnel sections. Its core components are angle sensors and range finders. [0003] Ranging information plays an important role in tunnel section scanning. According to the principle of ranging, it can be divided into triangulation method,...
